HOROMETER is designed for demands of professional users and watch collectors. We developed a new device which is able to involve the useful functions of other devices, while HOROMETER has new and unique abilities, too. Also, the aim of development of this device was to give useful measuring equipment not only for professionals, but also for the watch–collectors. So, it was very important to develop a device with unique measuring capacity and high level of cost-value rate. Design of HOROMETER has new features: Small (palm-size), Smart (User Friendly Software), Portable and Multifunctional.
